JOHN F. FOSS, OF LOWELL, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 228,809, dated June 15,1880.

Application filed December 8, 1879.

To all whom it may concern:

Be it known that I, JOHN F. Foss. of theV city of Lowell, county ofMiddlesex, and State of Massachusetts, have invented a new and usefulImprovement in Fliers for Spinnin g-Mation.-

The object of my improvement is to provide a spindle to run in the flierof a Speeder which shall be shorter than those heretofore used; tocombine with such a spindle a quill, which shall be rotated by thespindle, and upon which the bobbin is placed, and upon which it moves asthe traverse of the machine raises and lowers it; to combine with theJdierof a speeder a quill which, by sustaining and strengthening itlongitudinally and perpendicularly, prevents its arms or side piecesfrom being sprung outward by their centrifugal force when the flier isin rotation; to combine with the flier of a speeder a quill extendingfrom the top to the bottom of the tlier on which the bobbin traverses,which can have its top swung out from under the flier to permit thebobbin carried upon it to be dolfed.

The nature of the invention will fully appear from the subjoineddescription, when considered with reference to the accompanyingdrawings, forming part of this speciiication. f;

side of this quill is formed a slot, f, extending In theaccompanyingdrawings, in which similar letters of reference indicatelike parts, Figure l is an elevation, partlyin section,of a spindle andflier embodying my invention. Fig. 2 is an enlarged elevation of aportion thereof in section, showing the construction of the end ofthespindle and a section of the quill and follower. Fig. 3 is an enlargedview, partly in section, of the top of the quill, the hollow nose, andsliding bolt.

A is the spindle, driven in the usual manner by a gear-wheel workingwith the bevel-pinion a. C is the sleeve attached to the flier, andhaving upon its lower end the flier-pinion c, which is driven by theusual bevel-gear wheel of such machine.

Between the gear c and the ilier the sleeve has upon it the journal c2,which forms the lower bearing of the flier H, which is composed of thebottom b, top b', and sides or arms b2.

The top b has a hollow nose, d, extending upward upon it, which formsthe upper bearing of the ier and permits the drawing or roving to becarried in to the bottom on the line of thel axis of rotation.

Below the upper bearing. and from the top b of the flier, depends ahollow nose, d2, carrying a sliding stud or bolt," g, which extendsdownward and is provided with a pin, g', which extends out through theslotted hole d4 made in the shell of the nose (Z2. By means of this pinor lug the bolt may be raised so as to be retracted entirely within thenose d2, which has its end on a plane at right angles to the axis of therotation of the dier, and forms a bearing-surface or socket, d3, uponwhich the quill hereinafter mentioned rotates. Between this hollow noseand the bottom of the iiier b is placed the quill or tube e, having' itscenter upon the line of the axis of rotation of the dier H, and havingbearings e2 upon its ends, upon which, when in position, it is free torotate.

The lower bearing is formed upon the end of the quill to lit a bearingor socket, d3, formed in the flier. The Lipper bearing is formed uponthe end of the quill, and in its interior, near the end into which thecylindrical bolt g lits and slides when the quill is in place. By thisarrangement the quill is retained accurately in place with its centerupon the axial line, regardless of the spindle within it. Upon one fromnear its lower end to a point near its center. In the hollow nose d2 isplaced a bolt or sliding stud, g, which, being forced upward, permitsthe top of the quill e to be swung out from under the hollow nose d2,and the bobbin B to be doffed or removed when full and an empty onesubstituted.

The bolt g may be made to project from the quill einto the nose d2 androtate with the quill instead of the flier without departing from thespirit of my invention.

Within the quill the spindle A rises and falls, as it has heretofore inthe iliers of such machines; but its upper end is removed, so that whenit is at the lowest part of the traverse it extends only into the quillto the lowest part of the slot, and its top is made somewhat smaller,flattened, and extended sidewise out through the slot in a toe or lug,a', and the bobbin rests upon the top of such tlattened and extendedpart. To form this toe or lug IOO the spindle is drawn down into a necksomewhat smaller than the body of the spindle, and the lug formed uponsuch neck has its upper edge curved downward and backward until unitedby the neck to the spindle, and its under edge is curved from the neckupward and forward at sufficient distance fromv the upper edge to permitof the end of the spindle being introduced through the iier before itsattachment to its sleeve and into the interior of the quill by firstinserting the toe, holding` theparts obliquely to one another, and, asthe toe passes through the iiier or into the slot in the tube, bringingthem parallel. The lu g will then extend out through the slot, and whenthe mechanism is in place the top end of the quill can be, as beforedescribed, swung out toward its slotted side from under the stud,against which its end bears, without disturbingits adjustment andwithout binding upon the spindle, as would be the case if the spindlecontinued its normal size to its end.

' Therefore when the spindle is at the lower part ofthe traverse theupper end ofthe quill can be swung out to permit of the dofng of thefull bobbin and the substitution of an empty one without in any waydisturbing the driving mechanism of the iiier or spindle.

NVithin the quill @is placed the tube h,which loosely ts its interiorand rests upon the top ofthe spindle, so that as the spindle descendswithin the quill the tube will follow it and prevent waste and dirt fromfalling into the interior of the quill through the slot above thespindle. As the spindle rises this tube, being no longer than theunslotted part of the quill, is lifted into such part and in no wayinterferes with the traverse of the spindle.

It will be observed that in place of thelong spindle extending upthrough the bobbin and carrying its weight and that of the cop formedupon it, and bearing unsupported all their weight and tendency tovibration and gyration, I have substituted a shorter spindle, whichbears only the weight, an d is not affected by any tendency which thebobbin with its load may have to vibrate or gyrate when in rapidrotation; that I have substituted in place of a spindle bearing the loadofthe bobbin and its cop, and which carried the load with the rise ofthe traverse farther and farther from the bearing of the spindle, aquill on which the bobbin, being raised by the spindle and carriedfarther' from one point of support, is taken toward another, and whichtherefore dan never be as far removed from a point of support as in theold structure, and is always between two such points, and being uponsuch quill, the vibration of the spindle can have little or no effectupon it 5 that in place of a flier whose strength and stiffness islimited to that of its arms, which cannot practically be greatlyincreased iu size because of their greater re' sistance to the air andthe greater power required to drive them when so strengthened, andbecause, with each addition of metal to strengthen the arms, thecentrifugal force, which is the primary cause of weakness, is augmentedinstead of diminished, and which, having such limit, limits the speedwith which the flier can be driven. I have substituted a Hier which isstrengthened without adding to the weight of its arms, and independentof the size of the arms, by having the material placed so near the aXisof rotation as to be but little affected by centrifugal force act- .Zngupon its substance, and which, being so strengthened, can be driven muchfaster with but little addition to the power, one in which the arms canbe made smaller in diameter without destructively weakening it, and one,therefore, capablev of being` run with less power; that I have produceda spindle in which the tendency to vibrate'and gyrate is greatly reducedby reason of the better support which it receives, and by reason of itsbeing shortened above its bolster-rail, as well as by the fact that alllateral or vibratory motion of the bobbin is kept from acting upon it;that I have arranged and supported the bob bin upon a quill so that thetendency to vibrate or gyrate on account of irregularities in its loadis greatly diminished, and that therefore I have produced a iiier forspinning roving which runs steadier, can be run much faster, an dproduces more and better rovin gin a given time than those heretofore inuse.

What I claim as new and of my invention I. In combination, the iier H,having the bearings cl3, with the quill e, wholly within the iiier, andprovided with end bearings, e2, substa-ntially as described.

2. In combination, the iier H, provided with the bearing-surfaces orsockets d3, with the quill e, which is provided with an end and exteriorbearing at its lower end and an end and interior bearing at its upperend, substantially as described.

3. In combination, the iier H, provided with the hollow nose cl2,containing bolt g, with the quill e, having the annular upper bearing,c2, within which the bolt g slides, substantially as described.

4. In combination, the quille, provided with end bearin gs e2, and theflier H, provided with bearing-surfaces or sockets d3, and theretractile bolt g, which forms a stud upon which the quill revolves atits upper end, substantially as described.

5. In combination, the flier H, provided with upper and lower attachedsleeve bearings, with the quill e and the spindle A, the quill beingdriven by the spindle, whereby thel bobbin may be doffed withoutdisconnecting the mechanism for driving the quill, substantially asdescribed.
